TSM Performance 5.5 vs 6.2

2011-10-26 Thread Druckenmiller, David
I need to show management that simply upgrading TSM from 5.5 to 6.2 will not cause a degradation in performance. I know a lot of upgrades are done by moving to new hardware. We don't have that luxury. We are currently running on AIX 6.1 on p520 server. I've already upped memory to 32gb. Any
